skills

i have a few questions on making some skills.(im trying to use as few triggers as possible)

first, i want to make a skill that is channeling, not be channeling specifically earthquake. how do i do that? if it cant be done is there an easy way to make it damage units as well.

second, i want to make a few skills that require a hero to be level 16. the highest number i can put into the minimum level thing is 10, how do i change that.

third and final, i want to make a spell exactally like the mentalists mana shield in enfo's team survival. im pretty sure you can do this somehow from just the normal spell without triggers but i dont exactally understand the values and what they do enough to make a spell identical. the only way i think would work now is some trigger that would say: event: hero x has skill y active, hero x gets hit. Action: subtract z mana. and make the actual spell free. ( for those who dont know the skill is a mana shield that reduces by a percent damage taken per hit for a certain amount of mana, for example lvl 10 of the spell takes the entire hit(100%) for 9 mana

for that earthquake I am afraid that you will have to use some triggers.

To set hero level max higher take out MiscData.txt or MiscGame.txt (can't remember) they are under either the Units\ or UI\ directory

To the third question I have no idea what you mean and I have never played enfo, sorry.

Why dont you base that spell off of something different? I dont dee any real reson just to use earthquake. Try changing the values of Flame Strike.
